Be it known that I, HARRY E. DOERR, a citizen of theUnited States, residing at St.
Louis, and State of Missouri, have inventedcertain new and useful Improvements in Truck Side Frames, of which the following is a specification.
My invention refers to side frames for.
car trucks.
vOne of the objects of my invention is toVV arrange the journal boxes with respect to the side frames to maintain the coupler at l proper height under various conditions of wear lmposed on, the truck wheels.
Another object is todo away with'the necessity of furnishing a car truck at the i sity. of 'introduction of shims due`to the wear of the wheels until needed. j
A still further object is to provide connections between truck pedestals and the journal boxes toV permit installation of shims to compensate for wear as needed.
side frame.
-such adjustable connections, it is possible A further object is to provide a novel journal box connection ,to permit vertical adjustment between the box and the sidev frame and for application of shims of varying thicknesses as lrequired and'to eliminate the necessity of carrying shims before needed.
l accomplish these and other objects by providing an adjustable connection between the truck side frame and the journal boxes,
such as an ear onl the side frame for cop'N eration with the slotted lug on nthe journal box and a bolt passing through the apertures to retain the journal box in'position on the By reason of the provision of `to vary the vertical relation between the journal box and the truck pedestal by introduction of shims above the journal box to maintain'the coupler at its proper height.
The present practice of compensating for wheel wear es ecially steel wheels, is to build the Aside ame with a member or. tie
bar extending underneath the journal box and spaced therefrom by interposed removable' shims. In the course` of several years,`
the wheels wear to such an extent as to make truing necessary, which truing reduces the diameter ofthe wheels, and would result in Y la lowering of the coupler, if provision were not made to' compensate for such reduction` in wheel diameter. Usually, one of the shims below the journal box is'removed and interposed between the top of the journal box and the truck pedestal. other period of years the wheels are again trued making necessary transfer of another shim from below the journal box to the top thereof. This arrangement requires that every truck be provided with at least eight shims at the time the truck is lbuilt and applied to the car, which shims increase the weightof the truck, the cost` thereof and the Weight to be pulled by the locomotive. It
is the object of my invention to overcome the use of shims before needed and I accomplish this as hereinafter more fully described.
To more fully understand the nature of my invention attention is directed to the drawings wherein,- i
Figure 1 is a fragmentary vertical section through a cast `steel frame showing the application of the preferred `form of myinvent-ion, j l j lFig. 2 is a section on line 2--2 of Fig. 1, and
Fig. 3 is a perspective view of the pre-y ferred form of shim employed.
For the purpose of illustrating my Invention l have shown a. portion of a truck side frame 5 which is preferably box llke 1n sectionV and is provided with a truck pedestal 6 comprising at one side a downwar y depending jaw 7. The side frame Includes the usualcompression and tenslon members 8 and 9, respectively. The journal box 10 1s of usual construction except that one s ide is provided with a projecting lug 11 having a verticallydisposed elongated slot L,1.2 theref in. The truck: frame is provided with a box like portion 13 having a hollow interlor and provided with a recess 14 adapted to receive the ear 11. A bolt hole 15 is provided therecar is built and put into service the truck Then, after anpedestal 6 rests directly on top of the jou'rnal box 10, the bolt`16 passing through the apertures 15 and the elongated slot .12 in the lug 11, on the journal box. This arrangement permits the journal box to be secured to the truck frame for adjustment and removal with respect thereto.
When necessar to true the wheels of the truck the removal7 of metal from the. wheels is compensated for by the provision of a shim 17 between the top of the journal box l0 and the truck pedestal 6, the thickness of the shim being made to correspond to the amount of metal cut from the Wheels to maintain the coupler at its proper height. Preferably, the shim is made with edge walls 18 for embracing the frame as shown in Fig. 2, and retaining same in position. The provision ot' the elongated slot 12 in the lug 11 permits the journal box to be moved vertically relatively to the truck frame and still function properly. Then after another period ot time more metal being taken from the wheels a thicker shiln 17a is introduced, the thickness of this shim corresponding to the thickness of the first shim plus the decrease in the diameter of the wheel due to the amount of metal cut from the wheel the second time. It occasion demands a third truing a third shim of proportionate thickness may be provided.
It is obvious that by using such an arrangement it will be unnecessary to load the trucks with useless material at the time of building but that when the trucks are being overhauled and the wheels trued, the proper size of shim may be applied, the thickness of the shim being made to correspond to the reduced diameter of the wheels. This results in a savingv in the original cost of the trucks and in avoiding initially adding useless weight. It also means that only enough shims are needed to fill the requirements at any particular truing of the wheels. The shims are easy to make and do not have to be carried in stock in great quantities as affords a convenient way of providing means for compensating for the wear of steel wheels without the necessity of initially overburdening the trucks with useless parts.
I am aware that modifications of such a device may be made and T intend to include such modifications as come within the scope of the appended claims.
I claim:
1. In combina-tion, a truck side frame having a pedestal jaw with apertured spaced walls, a journal box having a lug with a vertically elongated slot and extending between said walls, said frame and box being relatively adjustable, and a bolt connecting the walls and lug, said connection permitting shims of varying thickness to `be inserted between the journal box and truck pedestal to vary the relative position therebetween.
2. ln combination, a truck side frame having a pedestal jaw with apertured spaced walls, a journal box having a laterally extending arm.v with a vertically arranged elongated slot, and means extending through said apertured spaced walls and elongated slot connecting said side frame and journal box to permit shims ofvarying thickness to be inserted between the journal box and truck pedestal for varying their relative positions.
Signed at St. Louis, State of Missouri, this 29th day of March, A. D., 1918.
